How Do Black Hole Works?
A black hole is an astronomical object with a
gravitational pull so strong that nothing, not even
light, can escape it.
1. Formation
- Black holes form at the end of some stars’ lives.
When a massive star exhausts its nuclear fuel, it
collapses under its own weight due to gravity. The core
collapse triggers a supernova explosion, blowing off
the star’s outer layers. If the crushed core contains
more than about three times the Sun’s mass, it
collapses into a black hole.
2. Event Horizon
-A black hole’s “surface,” called its event horizon,
defines the boundary where the velocity needed to
escape exceeds the speed of light. Matter and
radiation fall in, but they can’t get out.
